Install
===================
1. unzip it to a directory you prefer, e.g. /path/to/UniFi
2. make sure you have mongod installed (out database server) for your platform
3. make sure /path/to/UniFi/bin/mongod points to the /path/to/mongod
4. to run it,
        cd /path/to/UniFi/
        java -jar lib/ace.jar start
5. to stop it,
        cd /path/to/UniFi/
        java -jar lib/ace.jar stop

It seems to work OK as long as you have the right context on the data and log directories.

 
$ java -jar UniFi/lib/ace.jar start
Port 8443 not available

 semanage port -m -t mongod_port_t 27117


BTW it seems that the dd-wrt can be installed on it but not for free.

Besides you do this at your own risk and expense.

And what about the "modprobe iwlwifi 11n_disable=[1248]",
does it have any effect on throughput?

In every case it ramped up to 54MBit eventually although it some cases it was very slow to do so.
